After protracted challenges to class certification status, in Merricks v Mastercard1 the U.K. Competition Appeal Tribunal (CAT) granted its first collective proceedings order (CPO). The claim remains huge, comprising 46.2 million consumers, but Mastercard successfully persuaded the CAT to narrow the class, potentially reducing the claim by £5 billion.
In December 2007, the European Commission (EC) found that by setting default interbank fees whenever consumers paid for goods or services using their Mastercard in the EEA, Mastercard restricted price competition between the banks and violated EU competition law.
Walter Merricks, the proposed class representative, commenced an extremely broad U.K. class action based on the EC decision. It claimed on behalf of approximately 46.2 million U.K. consumers, seeking £16 billion (including interest). The claim was an indirect one, made not by retailers that actually paid Mastercard’s fees,3 but by U.K. consumers for the allegedly inflated prices they paid when retailers passed on allegedly unlawful charges.4
The CAT, which must rule whether claims are suitable for collective proceedings, initially refused a CPO. It felt that the class was too wide, and the proposed distribution methodology inadequate. The English Court of Appeal, upheld by the UKSC, decided that the CAT had not applied the correct test.5
The UKSC held that the test for CPOs was a relative judgement as to whether claims are “suitable” for collective proceedings ― whether the claims are more appropriately brought as collective proceedings rather than individual proceedings. The same logic was applied in deciding whether a claim is “suitable for an award of aggregate damages” (a relevant factor in the overall assessment of suitability). An aggregate damages award need only be more suitable than “a multitude of individually assessed claims for damages”. The UKSC judgment therefore significantly circumscribed the CAT’s gatekeeper role.
On remittal, Mastercard did not oppose certification. Nonetheless, it is instructive that Mastercard persuaded the CAT to narrow the claim.
The principal claim was estimated by Merricks to be worth up to £7.2 billion. As of January 2021, the interest relating to this claim amounted to: £6.6 billion in simple interest, or £8.8 billion in compound interest (i.e., £2.2 billion more than the simple interest claim).
As a matter of English tort law, compound interest can be award as damages, provided that it is specifically claimed and justified. Merricks argued that all members of the class at some point during the 16-year period would have borrowed money or had savings, so they would have paid interest and/or lost the opportunity to earn interest to the extent that they were deprived of money due to Mastercard’s alleged overcharges.
The CAT considered that, in the context of a “gargantuan” interest claim worth up to £8.8 billion, a plausible or credible methodology needed to be put forward at the certification stage; and no such methodology had been put forward as to the amount of the overcharge that would have been saved and/or used to reduced debt, rather than spent, by consumers. This was particularly significant given that the average class member’s loss is thought to be in the region of £10 per year, accruing over the course of the year, so it was not readily inferable that the money would not simply have been spent.
The CAT, therefore, found the compound interest claim not to be “suitable” for collective proceedings and excluded it from the CPO. Instead, the class may seek simple interest on a statutory basis.
Class Definition – Deceased Persons
Merricks’s claim form expressly acknowledged that the class definition excluded the estates of individuals who met the substantive definition but died before the “domicile date”.6 The notice of the CPO application made specific reference to the claim being on behalf of individuals “who are living in the UK at the time the claim is allowed to proceed”.
Upon the remittal of the case to the CAT, Merricks confirmed that he wished to include deceased persons in the class, thereby increasing the class size by approximately 13.6 million, to 59.8 million (i.e., by 29%). Merricks also recognised that the expert calculation of aggregate damages included losses allegedly suffered by now-deceased persons and, therefore, to the extent they are not included in the class, the damages calculation would need to be reduced. The CAT rejected the argument that the existing class definition included deceased persons and, consequently, Merricks sought permission to amend the claim form so as to include “persons who have since died”.
The CAT refused permission, on various grounds. In particular, whilst the CAT saw no difficulty in principle in a class definition including the estates of deceased persons, claims could not be brought on behalf of deceased persons themselves, as opposed to their estates, and, therefore, Merricks’ proposed amendment was incoherent. The CAT also decided that, in the present case, limitation rules precluded the inclusion of persons who were deceased before the claim form was issued. However, the CAT remarked that Merricks could apply again to amend the claim form and CPO to include the claims of the representatives of estates of persons who die/have died during the course of the proceedings.
Litigation Funding Arrangements
Merricks has entered into a litigation funding agreement (LFA), pursuant to which Merricks has access to £45.1 million for his costs and disbursements, and has adverse costs cover of £15 million. Mastercard did not challenge the adequacy of the quantum of adverse costs cover, but objected on the basis that the LFA expressly excluded third-party rights, arguing that it might not be able to enforce a costs award in its favour. The CAT was sympathetic to Mastercard’s concerns and, accordingly, Merricks’s funder agreed to undertake to the CAT that it would discharge a liability for costs ordered against Merricks.
The CAT also emphasised that, despite the limited nature of Mastercard’s objection, it would scrutinise the LFA more fully, saying it is “for the Tribunal to be satisfied as to the position since the Tribunal has responsibility to protect the interests of the members of the proposed class, and their interests are of course not necessarily aligned with the interests of Mastercard”. The CAT found that, following some amendments, the Merricks LFA was satisfactory.
Looking beyond Merricks, we are likely to see judgments on numerous other applications for CPOs before the end of 2021 raising interesting and novel issues:
Class Actions in Non-Follow-On Claims
Boundary Fares involves alleged double-charging by passenger train operators. There was no prior competition authority decision, and the nature of the alleged violation is an obscure one, so this CPO application is brought on a standalone basis.
An opt-out class action without any underlying infringement decision is arguably the most extreme category of antitrust class action that could proceed under the CPO regime, particularly where such action relates to behaviour that, even if established, is not readily identifiable as anticompetitive. That is relevant to the CAT’s decision on whether claims should be opt-in (where individuals only form part of the class if they expressly elect to join the action) or opt-out (where individuals are part of the class unless they expressly opt out), because one factor is the strength of the claims. The CAT’s Guidance states that follow-on claims, where a competition authority has decided that there was an infringement, generally will be strong enough for this criterion not to be in question. For a standalone claim, however, showing the strength of the claim is a potentially significant hurdle, to the extent that proceedings may only be permitted to proceed on an opt-in basis.
The would-be defendants in Boundary Fares have also argued that, whilst Merricks shows that individualised damages calculations are not necessary, it does not follow that causation and liability need not be established on an individual basis. This shows another respect in which, for standalone cases, the onus on the proposed class representative will be greater.
Alongside the CPO application, the CAT heard summary judgment and strike-out applications brought by the proposed defendants. This follows the UKSC’s remarks in Merricks that the CAT’s summary judgment and strike-out powers are an appropriate mechanism for the CAT to exercise “merits-based control over collective proceedings” at a pre-trial stage (e.g., at the CPO hearing). This gives rise to the possibility that the claims could be found eligible for inclusion in collective proceedings but simultaneously are struck out or dismissed summarily.
Finally, the CAT expressed concerns that, where small amounts are due to class members and it is difficult to establish that they are entitled to a share of an award, the real winners may be litigation funders, who might profit from any unclaimed portion of an award. Therefore, the proposed class representative was requested to provide information about the funder’s remuneration structure and the typical level of “take-up” by class members in North American class actions.
In FX and Trucks, the CAT is facing a “carriage dispute” between two competing CPO applications. In March 2020, the CAT decided in the FX case that the carriage dispute should not be addressed as a preliminary issue, so both CPO applications were heard in July 2021. In each of FX and Trucks, it will be interesting to see whether one, both or neither of the competing applications is successful, and to gain greater insight about the CAT’s approach to competing applications.
Other Class Action Mechanisms
Merricks is the first English opt-out class action to be certified, but the CPO regime is not the only avenue through which opt-out class actions may emerge. Last year’s decision by the English Court of Appeal in Lloyd v Google7 suggested a generous approach to pursuing a representative action under CPR 19.6, deciding that four million iPhone users had the “same interest” in claims for alleged data protection breaches. The UKSC recently heard Google’s appeal in this case, and the judgment is expected later this year. The UKSC’s decision in Lloyd v Google regarding the meaning of “same interest” will have implications across the spectrum of disputes. A broad approach to CPR 19.6 could open the floodgates to opt-out class actions in the U.K.
Each aspect of the CAT’s decision shows that, whilst the UKSC has established a threshold for “suitability” of claims for collective proceedings, the CAT should be expected to take a proactive and rigorous role in considering whether to grant a CPO and, if so, what scope is appropriate.
Notwithstanding Mastercard’s success in the present judgment, Merricks illustrates a noteworthy feature of the developing U.K. class action system: Indirect claims by a huge consumer base seeking very substantial sums can proceed to certification with relatively few obstacles. Those indirect claims can be (and often are) pursued in parallel with claims brought by commercial counterparties against the same defendants. Mass consumer classes may increase pressure on defendants to come to terms with the class rather than expose themselves even to a low risk of an adverse judgment at trial. The risk of these in terrorem settlements was recognised by the UKSC in its Merricks ruling.
Merricks shows that the CAT’s gatekeeper function will be a significant feature of the CPO regime, notwithstanding the UKSC's suitability test for certification. The upcoming decisions, both in the antitrust sphere and beyond, will be formative in the development of the U.K.’s class action landscape.
